Glass design charts are available for annealed, monolithic glasses. In order to use these design charts, strength of a laminated glass unit needs to be adjusted by a strength factor. This paper presents a study on strength factor and the effect of various factors oil the strength factor, like ambient temperature, width and length of the beam. The effect of nonlinearity on the strength factor is also investigated by considering the nonlinear behavior of fixed end laminated glass beams since the simply supported glass plates behaves nonlinearly. From the study, two factors are crucial in the estimation of relative strength of laminated glass with respect to monolithic glass: one of two factors is the plasticizer content and therefore the transition temperature of the PVB layer used in the manufacture of laminated glass unit, and the other is the effect of nonlinearity as observed in the analysis conducted with fixed end beams in this study.

OPTIMUM DESIGN OF FRAMES ERBATUR, F; ALHUSSAINY, MM (Elsevier BV, 1992-12-03) In this paper optimum design of frames is discussed. Specifically, minimum weight design of steel frames in the elastic range of material behaviour is treated. The solution algorithm is designed and programmed for use on micro-computers to suit a design office environment. Stress and slenderness constraints are considered, however displacement constraints may readily be implemented. Three examples are given and the results are discussed.
Guided stochastic search technique for discrete sizing optimization of steel trusses: A design-driven heuristic approach Azad, S. Kazemzadeh; Hasançebi, Oğuzhan; Saka, M. P. (Elsevier BV, 2014-04-01) This study presents a design-driven heuristic approach named guided stochastic search (GSS) technique for discrete sizing optimization of steel trusses. The method works on the basis of guiding the optimization process using the well-known principle of virtual work as well as the information collected during the structural analysis and design stages. The performance of the proposed technique is investigated through a benchmark truss instance as well as four real-size trusses sized for minimum weight accordi...
Optimum design of high-rise steel buildings using an evolution strategy integrated parallel algorithm Hasançebi, Oğuzhan; Kurç, Özgür (Elsevier BV, 2011-11-01) The present study addresses a parallel solution algorithm for optimum design of large steel space frame structures, in particular high-rise steel buildings. The algorithm implements a novel discrete evolution strategy optimization method to effectively size these systems for minimum weight according to the provisions of ASD-AISC specification and various practical aspects of design process. The multitasking environment in the algorithm rests on a master-slave model based parallelization of the optimization ...
CHAOTIC DYNAMIC ANALYSIS OF VISCOELASTIC SHALLOW SPHERICAL-SHELLS Karaesmen, Engin; ILERI, L; AKKAS, N (Elsevier BV, 1992-08-03) This paper investigates the dynamic behaviour of a shallow, viscoelastic, spherical shell under a harmonic excitation. The time evolutions of the response of the corresponding nonlinear dynamical system are described by the phase portraits and the bifurcation of the parameter dependent system is studied numerically so as to identify qualitative changes in the phase portrait. The viscoelastic shell, having more than one equilibrium configuration for some problem parameters, shows periodic and/or random-like ...
BCC single crystal plasticity modeling and its experimental identification Yalçınkaya, Tuncay; Geers, M.G.D. (IOP Publishing, 2008-12-01) A crystal plasticity model for body-centered-cubic (BCC) single crystals, taking into account the plastic anisotropy due to non-planar spreading of screw dislocation cores is presented. In view of the longstanding contradictory statements on the deformation of BCC single crystals and their macroscopic slip planes, recent insights and developments are reported and included in this model. The flow stress of BCC single crystals shows a pronounced dependence on the crystal orientation and the temperature, mostl...
